Look to acquire uniform material (5)
I believe the answer is:
gauze
'material' is the definition.
(gauze is a kind of material)
'look to acquire uniform' is the wordplay.
'look' becomes 'gaze' (gazing is a kind of looking).
'to acquire' is an insertion indicator.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'gaze' placed around 'u' is 'GAUZE'.
(Other definitions for gauze that I've seen before include "first-aid material" , "Thin woven material used in bandages" , "Openwork fabric - fine mesh" , "Very fine wire mesh" , "Cloth for bandage" .)
